Specification of Letters Patent.

Patented Jan.13, 1920.

Application filed October 10, 1919; Serial No. 329,739.

To all whom it may concern:

Be it known that 1, Answer V. POLL- MILLER, a citizen of the United States, residing at Marceline, in the county of Linn, State of Missouri, have invented a new and useful Semaphore-Signal; and I do hereby declare the following to be a fu11, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to semaphore signals and has for its object to provide the standard upon which the semaphore arm is pivoted with a semicircular plate, which plate forms a background for the semaphore arm and is adapted to be painted a contrasting color to the semaphore arm, thereby in creasing the Visibility of the semaphore arm.

A further object is to provide a background for the semaphore signal comprising a semi-circular plate adapted to be secured by U-bolts to thesemaphore standard so as to form a background of a contrasting color to the semaphore arm.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a frontelevation of the semaphore signal showing the background applied thereto.

Fig. 2 is a side elevation of the signaland background.

Fig. 3 is a detail sectional view taken on line 33 of Fig. 1. r

Referring to the drawings, the numeral 1 designates a standard to the upper end 2 of which a semaphore arm 3 is pivoted as at 4:. The semaphore arm 3 may be controlled by any suitable mechanism through the medium of the rods 5, which are pivoted to the end 6 of the arm 3. Standard 1 is usually round, however, it is to be understood that said standard may be of any shape and cross section.

is painted various colors to indicate various meamngs; however, where the semaphore 1s used on railroads the color of the arm may The semaphore arm 3 at the present time so blend with its surroundings that it cannot be seen for a great distance; therefore, to overcome this objection a plate 7 forming a back ground is provided. Plate 7 is adapted to have its surface 8 painted a color which will be a contrast to the color of the arm 3 thereby increasing the visibility of the semaphore arm 3 so that the signal may be readily seen from a distance. Plate 7 is preferably semi-circular and has its central point in registration with the pivotal point 4 of the semaphore arm so that as the semaphore arm 3 is moved to various positions the background will be in registration there- A with. The upper end 2 of the standard 1 is painted the same color as the background so that the entire vision behind the semaphore arm3 will be of a contrasting color. The background is secured to the standard by means of U -bolts 9 which arch the upper end 20f the standard and have their ends passing through apertures in the background and on which ends nuts 10 are threaded by means of which U-bolts and nuts the background may be securely fastened to the upper end of the standard 1. To additionally secure the background 7 to the standard, rivets 11 are placed through the upper end of the standard and the background and by the use of the U-bolts in connection with the'rivets it will be seen that the rivets will be prevented from splitting, the standard during a high wind and also be prevented from being twisted out of the same vertical plane as the semaphore arm.

From the above it will be seen that a back ground for a semaphore signal is provided which may be easily and quickly applied to a semaphore standard and one wherein, by its particular securing means, the swaying of the same will be prevented and the splitting of the upper end of the standard by the rivets prevented by the use of the U-bolts. V

A lamp bracket 12 is secured to the upper end 2 of the standard on which bracket if so desired the lamp may be placed so as to radiate light on the background at night.

The invention having been set forth what is claimed as new and useful is A background for semaphore signals comprising a semi-circular plate having its central point in registration with the pivotal point of the semaphore arm, said plate be-' ing painted a contrasting color to the semaphore arm, rivets passing through the semaend of the standard under wind pressure on phore standard and the background plate the background plate. for securing the background plate in the In testimony whereof I have signed my same vertical plane as the semaphore arm, name to this specification in the presence of 5 U-goltslafching tlie uppeCr1 end o f the1 stand}; two subscribing Witnesses.
